I drive an 09 wrx and I recently got new door speakers for my birthday. Kicker DS series.

While I was at class my brother installed the new door speakers. They are just kicker speakers, nothing to special just plug and play as far as I was concerned.

When I got home he told me he thinks he blew a fuse because my power windows no longer worked. Checked the fuse and it was ok. He then informed me he didn't unplug the battery either during the install.

After some investigating and looking around we couldn't figure out what was wrong, there is a click noise that happens 20-30 seconds it seems like, and when it happen my rpms drop maybe a couple 100 for half a second then come back up and if my dome light is on it dims for a half second when it clicks. Along with my day time running lights.

If I am holding all of the window buttons down on the drivers side when the click happens only the front passenger window rolls down but just for that half a second during the click then it stops. Not sure if its some kind of relay or ground wire or something else.

I figured I'd post on here before my next step which would be taking it to the dealership at my brothers expense. If anyone has any idea on what could be wrong or knows how to fix it I'd greatly appreciate it.

The power windows use a circuit breaker to protect the circuit and not a normal fuse. This way if the power gets shorted the breaker will reset itself and hopefully the short has cleared also. The click you hear is most likely coming from the breaker as it trips and removes power to the circuit. From what you say it sounds like there is a short on the power window circuit. If the clicking occurs even if you are not trying to move the windows then the short is before the switch console in the driver's door.

Check the connector at the power window switch. In the drivers door. Possibly when the door panel was removed the plug could have been put back in and a pin has bent over making contact w another. Iv seen it happen many times.

I'll check that out thanks. Should I check all of the pins at each door?

I would tend to think the short is located before the switch box in the driver's door. If you have a lock out switch for the window controls see if that changes things. If it does then it may indicate the trouble is at one of the other door controls.

The advice that Chickennecks? gave is real good and it may be the real problem here.
